Abstract: A connector comprises a contact pin, a housing into which the contact pin is inserted, and a retainer. The contact pin includes a contact point portion formed on an end thereof and defining an opening adapted to receive a mating contact, and an engagement portion. The engagement portion is defined at least partially through the contact point portion, and includes a continuous opening formed partially through a side wall of the contact point portion in a height direction and partially through a top wall or a bottom wall of the contact point portion in a width direction. The retainer is insertable into the housing in a direction intersecting the direction of insertion of the contact pin. The retainer is adapted to be inserted into the housing and engage with the engagement portion of the contact pin to secure the contact pin within the housing.

Abstract: A connector comprises a first housing, a cam member, and an operation lever. The first housing has a mating portion configured to mate with a second housing of a second connector. The cam member has a cam groove configured to mate with a cam pin provided on the second housing. The cam member causes the second housing to mate with the first housing by sliding in a lateral direction intersecting with a direction of mating to draw the cam pin into the cam groove. The operation lever slides the cam member according to a turning operation. A nipping portion of the connector nips the cam pin in the cam groove when the cam member slides up to a mating completion position at which mating of the second housing with the first housing is completed.

Abstract: A connector assembly that includes a first connector and a second connector. The first connector has a spring member press-fitted into a housing thereof. The second connector has a groove in a housing thereof. At the time of mating, the spring member is inserted in the groove in a mating direction to be deformed elastically in a direction intersecting the mating direction. Then, with the spring member of the first connector elastically deformed in the groove of the second connector, looseness between the housing of the first connector and the housing of the second connector is prevented.

Abstract: A connector having a housing, a slide member, and an operation lever. The slide member slides in response to operation of the operation lever. The slide member has a guide projection and slides while the guide projection is guided in a guide groove of the housing. The slide member has a cam groove that receives a cam pin in a second connector and the slide member, by sliding, performs mating with the second connector. The slide member has a first nipping portion that nips the cam pin when it slides to a completely mated position. The housing has a second nipping portion that nips the guide projection of the slide member when the slide member slides to the completely mated position.

Abstract: An electrical connector is provided and includes a housing and a terminal. The housing includes a terminal receiving passageway and a lance extending into the terminal receiving passageway. The terminal is inserted into the terminal receiving passageway and includes a top surface facing the lance and a holding portion extending from and above the top surface.
